Specification of Letters Patent.

Application led July 16, 1914. Serial No. 851,307.

To all whom t may concern.'

Be it known that I, ORLaND L. IHRIG, a citizen of the United States, residing at Sunnyvale, in the county vof Santa Clara and State of California, have invented a certain new and' useful Improvement in Means for Supplying Air and Water to Carbureters, of which the following is a specification.

My invention relates to improvements in air and water supplying means for carbureters for combustion engines and the like.

Among its objects are to provide means for cleaning or washing the air which is subsequently to be conveyed to a carbureter for a combustion motor and also to supply moisture to this air and water to the carbureter to promote satisfactory combustion of the heavier fuel oils and the like.

It is illustrated diagrammatically in one form in the accompanymg drawings, wherein- Figure lv is a diagrammatic view of an engine and carbureter with my device attached; Fig. 2 is a vertical section through my device; Fig. 3 is a section along lineB-B of Fig. 2; and Fig. 4 is a section along line -1-4of Fig. 2. Fig. 5 is a detail section through the side wall of my device adjacent the bottom thereof.

Like parts are indicated by like letters throughout the several iigures.

A is a cylinder housing or tank closed at the bottom and open at the top.

A1, A1 are air intake apertures in the wall of the tank A.

A2, A2 are small overflow apertures slightly abovel the normal liquid level.y

A3 is al clean-out valve at the bottom of the tank.

A4 is a filler pipe controlled by a plug valve A5 held normally closed by a spring A6 adapted to be opened by the weight of the float A7 when the liquid level drops below the predetermined level.

B is a cylinder having a closed top B1 flanged as indicated to rest upon and be supported by the upper edge of the outer tank A. The cylinder B is of such height that when supported by this flange in the cylinder A as indicated the lower edge remains above the bottom of the cylinder A. B3 are spacers arranged about the periphery of the cylinder B along its lower edge adapted to engage the cylinder edge to center the cylinder B in the cylinder A. These spacers which are hollow triangular members, as indicated, extend down below the bottom of the cylinder B immediately above the bottom of the cylinder A and they communlcate with the interior of the cylinder vB through the apertures B4.

B5 is a conical baille plate mounted in the cylinder B and terminating in line with the apertures B4 so that liquid which finds its way to the outer or upper side of the baille plate will run 0H to the bottom of the cylinder or tank A. i

B5 is a screen located at the bottom of the cylinder A. Centrally disposed in said cylinder and together with the screen partially closed at the bottomvthereof is a housing B7 which incases the plug feed mechanism as indicated and is provided with a vent pipe B5.

' B9, B10 are screens extending across the cylinder B separated one from the other and located above the normal liquid level which has the screen BG located below the normal liquid level.

B11 is a horizontal baille plate located above the conical baille plate B5 spaced from and supported upon and by the bracket B12 to form the annular passage B13 between the plate and Walls.

C is a discharge elbow or pocket leading from the top of the cylinder B and communicating by means of a flexible connection C1 with a carbureter air intake pipe C2 on a combust-ion motor C5.

C4 is a circulating water pump on the combustion motor C3 which supplies cool-- ing water thereto in the usual manner.

C6 is a pipe leading from the cooling system pipe C5 to one branch of a T C?.

C8 is a pipe leading from the other branch in the T to supply water to the filler pipe A4.

C is a water supply nozzle discharging from the remaining branch of the T into the interior of the elbow C.` It is controlled by a needle valve C1".

It will be evident that while I have shown in my drawings an operative device still many changesmight be made both in size,

shape and arrangement of parts without deare as follows: My device is prepared for use by first inserting the upper or inner cylinder into thev outer cylinder, connecting the discharge mouth or elbow in the cylinder to the engine carbureter by ay suitable preferablyvfiexible connection. he engine circulating system is then'connected up to outside cylinder.

'the float will be raised and the spring will be able to close the plug valve. At this point or level the lower screen carried adjacent the bottom edge of the cylinder will be immersed and the inside of the inner cylinder thus forms what is in effect a vacuum l chamber open tothe carbureter through the discharge elbow but closed to the outer cylinder by the Water. The engine is then started. As it operates it draws air from the inner cylinder producing therein a vacuum. Air meanwhile rushes down from 'the openings in the wall of the outer cylinder and is drawn into the water supply bubbling up through the screen, which thus assists in breaking up and mixing the air and water so that the air is eifectually Washed and all dust ,and di'rt in the air is -left with the water and the air passes up,

through the two upper screens which are kept thoroughly moist by the bubbling up of the water carrying with it a certain amount of water in suspension. This water is taken out of the air by the two bale plates. This air passes in a thoroughly Washed lbut moist condition out from the bottom of the chamber into the conduit which conducts it to the carbureter. Experience shows that even this moist air does not carry enough Water and it is desirable to supply additional Water, the supply of which is controlled by the needle valve. The amount of moisture carried by the air can be controlled but this 'does not interfere with the liquid level in the bottom of the tank and this water,v` moreover, as it does not come 'from the tank is clear and pure and not openings in the bottom which are suilicient to carry o' any excess iiow of water so that there is no'danger of the device filling up with Water and thus becoming inoperative. My device may be cleaned by withdrawing the inner fromv the outer cylinder and draining the water from the drain at the bottom.

I claim:

1. An air washer comprising a receptacle adapted to contain a quantity of liquid, an air inlet passage opening below the surface of said liquid, an air outlet passage arranged at the top of said receptacle, an inverted funnel contacting at its lower end with the sides of the receptacle, and a baiile plate of less diameter than the receptacle arrangedabove said inverted funnel, and a conduit extending from the annular space between the funnel and the receptacle to a point below the surface of the said liquid.

2. An airwasher comprising a cylindrical housing closed at the bottom, a casing closed at the top and open at the bottom suspended within said housing its bottom being lifted above the bottom of the housing and upwardly, an extended truncated 'ange mounted within the casing and open at the top, a bailie plate above the open top of the cone located Within the housing and extending outwardly beyond the open mouth of the cone, a discharge pipe leading from the y casing above the baifle plate.

3. An air washer comprising a cylindri-y cal housing closed at the bottom, a casing4 closed at the top and open at the bottom sus` pended within said housing its bottom beingv lifted above the bottom of the housing and upwardly, an extended truncated flange mounted within-the casing and open at the top, a baille plate above the open top of the cone located within the housing and extending outwardly beyond the open mouth 0f the cone, a discharge pipeleading from the casing above the baille plate, the Wall of the casing being apertured above the cone, a discharge pipe located upon theoutside wall of the housing communicating withV said aperture and discharging downwardly beneath the lower edge of the housing.

In testimony whereof, I aiiix my siUnature in the presence of two witnesses this 5ith day of July, 1914.
